Systems analysis and design tutoring - Data flow diagrams etc...

Hello,

I require some tutoring/teaching regarding Systems Analysis and Design,

namely, i require you to teach me how to determine use cases from a narrative and then convert that into a Data flow diagram, (context and level 0) i also need to be able to normalise tables and draw entity relationship diagrams.

I will pay the £17 in this job for the initial session in which i'd like to do DFD's and then will pay subsequently after that for additional topics.

thanks!
